Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
Fastball
Sink+
A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.
Fastball
Rise+
A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

McHenry County JC signee. It was a quality performance for Korosa in their loss to Homewood-Flossmoor, throwing six innings on the mound with four strikeouts, two walks, three unearned runs and five hits allowed.
McHenry County JC commit, was strong in his brief start for the Porters on Friday afternoon. Korosa stands in at an imposing 6-foot-2, 216-pounds and is an athletic mover down the mound. Despite only two innings of work, Korosa used a steady dose of all three of his offerings throughout the game. His fastball sat 83-86 mph (T88) with arm-side run playing like a 2-seam. He mainly went to a slurve-type breaking ball as his out-pitch that induced whiffs and weak contact from opposing hitters. Korosa also tossed in a short arm-side fading changeup at 77-80 mph. The future Scot turned in a final line of: 2 IP, H, 0 BB, 0 R, 3 K; and will look to be the ace for the Porters throughout the spring.
Verbally committed to McHenry County CC.
